Abstract (en)

[origin: WO2004060599A1] A process for the manufacture of an explosively-bonded composite structure (100) comprising a substrate (12), a metallic cladder (14) and an intervening interlayer (28) between the substrate (12) and the cladder (14), the cladder (14) and the interlayer (28) having a waveless interface therebetween, the process comprising (A) forming a non-bonded composite structure (100) comprising in combination, (a) a substrate (12) having a first side; (b) an interlayer (28) of a material compatible with the substrate (12), and having (i) a thickness Tl;(ii) a mass Ml; (iii) a first side adjacent to the substrate (12),and having (i) a thickness T1;(ii) a mass Ml; (iii) a first side adjacent to the substrate (12) at a distance Dl, therefrom; and (iv) a second side; (c) a cladder (14) having (i) a thickness TC;(ii) a mass MC; (iii) a first side adjacent to thesecond side of the interlayer (28) at a distance D2 therefrom; and (iv) a second side; and (d) an explosive mixture (16) adjacent the second side of the cladder (14); and wherein Dl is equal to or less than 2T1; D2 is equal to or less than TC; and MC is equal to or greater than Ml; and (B) detonating said explosive mixture (16). Tae method produces one or more totally flat interfaces,which avoids the formation of deleterious waves and the associated inherent problems of cracking and incorporated intermetallics. The method also allows of the use of thin interlayers (28), which is of value when such interlayer materials are expensive.
